It’s been three long years since the Lubuntu team promised us that they’d drop the LXDE desktop environment in favor of the more modern, Qt-based LXQt, but now it looks like it’s finally happening. Lubuntu 18.10 will be the first release to ship with LXQt as default desktop environment instead of LXDE, according to Simon Quigley. The first release that was supposed to move to LXQt by default was Lubuntu 15.10 a.k.a. the Wily Werewolf. The Lubuntu team from back then announced that Lubuntu 15.04 (Vivid Vervet) would be the last release to ship with LXDE as they prepare the migration to LXQt, but it never happened, even to this day.
